It would be helpful if you provide more information about how these characters should be entered on the bilingual file. Could you please post some right and wrong samples?
Here is a string from the xml that shows when we need to know if a excape character is missing:
Il sistema dispone di %1$d dispositivi che saranno inutilizzabili dopo l\’eliminazione del sistema. Sarà necessario aggiungere nuovamente tali dispositivi a un sistema per utilizzarli.
The above string would not have the string ID showing in TRADOS but included just in case it helps.
We are trying to figure out a way to know if a apostrophe or quote is missing the “” (backslash). So when we run the tool for Regex it will flag these that don’t have it.
Missing escape character before apostrophe:
Target: ' -\'
Search mode: Simple
PowerSearch: On
Missing escape character before opening or closing quotes
Target: """" -"\"""
Search mode: Simple
PowerSearch: On
Normalize Native Characters: On (to find all types of quotes)
